New equipment, high humidity at night

I'll start off by saying I live in a fairly dry area .

With that being said I switched my setup around, I put in a 4 ton mini split and got a co2 controller.

Now my rh is 45 when lights are on. It gets as high as 75 when it's dark.

So I was thinking that I should put a timer on my CO2 controller so that way my burners only on 12 hours out of the day.
Did that. Hope that helps. Won't know until tomorrow.

I also got an average dehumidifier to run during the night. But I doubt it's big enough to do anything

My mini split pulls a lot of water. Easily 10 gallons a day, probably closer to 15

Also my counts are much higher and I use Coco.

Now I've just set it to auto 77° in my environment is perfect except for this rh but I have to fix it because I can't have Bud rot in week 10.

Now there's an option and a timer to program the mini split but I'm scared that I'll do it and it will just stay in duey mode.

Almost like I'm going to have to spend the night there to make sure it works properly lol.

Any input or ideas?
 
Does the split unit have a dehumidify mode where it doesn't heat or cool? Is the high humidity at night when the lights are off? It could just be the mini split isn't running and extracting moisture when it doesn't need to cool the space.
